Allozymes as diagnostic characters of sibling species of Drosophila.
Considerable enzyme variation that is genetically controlled exists within and between natural populations of Drosophila. Our studies of two groups of sibling species show that allozyme differences can be used as species-diagnostic characters. A locus is defined as diagnostic if an individual can be correctly assigned to one of two species with a probability of 99% or higher. Between 15 and 32%...
متن کاملEffects of Lead on Ultrastructure of Isoetes sinensis Palmer (Isoetaceae), a Critically Endangered Species in China
Isoetes sinensis Palmer (Isoetaceae) is a critically endangered fern that is a marsh plant (that is an aquatic or amphibious plant) in China. To evaluate damage or influence of lead (Pb) on cell ultrastructure in I. sinensis, we used 2000mg·L-1 Pb(NO3)2 solution to treat I. sinensis for 35d, and used transmission electron microscope (TEM) to observe the cell ultrastructure of leaf blades and ro...
متن کاملA review on the nectar scale characters in some species of Ranunculus in Iran
Ranunculus L. with about 600 species is the largest genus in the Ranunculaceae. Problems in the taxonomy of the genus are due to high variability and polymorphism among different individuals and populations of certain species. Morphological characters of nectar scale have been considered as valuable taxonomical characters in some perennial species in some groups (Praemorsa, Grumosa, Rhizomatosa...
متن کاملPalynological analysis of Sphaeropteris gardneri (Cyatheaceae, Pteridophyta).
The spore morphology and wall ultrastructure of Sphaeropteris gardneri (Hook.) R.M. Tryon from Brazil were analyzed with LM, SEM and TEM. The spores are trilete with an ornamentation formed of short low ridges with spines in their margins. The exospore is 2.5microm thick, two- layered in section and single or branched channels are present. The perispore is 1.2microm thick and two-layered. The i...
متن کاملPopulation structure of three Psammodromus species in the Iberian Peninsula
The knowledge of a species' population structure is essential for the development of adequate conservation actions as well as for the understanding of its evolution. The population structure is unknown in all species of the Genus Psammodromus, including the Western Sand Racer (Psammodromus occidentalis; a recently described species), the Edward's Sand Racer (P. edwardsianus) and the Spanish San...
